1914811 - You transfer data from your ECC to your SCM System and you get the error message SR053? What does that mean?

You use an ECC system connect with a SCM system and you transfer data (master and transaction data) via core interface (CIF). The queue stops with a SYSFAIL and an error message SR053.
What does that mean? What must be checked next and how? How can I find out which object is creating the error message.
